Maverick and Scout are both trained on up to 40 trillion tokens on data encompassing 200 languages (with specific fine-tuning support for 12 languages including Arabic, Spanish, German, and Hindi).</p> <p>For deployment, Llama 4 Scout is designed for accessibility, fitting on a single server-grade GPU via on-the-fly 4-bit or 8-bit quantization, while Maverick is available in BF16 and FP8 formats. These models are released under the custom Llama 4 Community License Agreement, available on the model repositories</p> <p>Getting started with Llama 4 using transformers is straightforward. Make sure you have transformers v4.51.0 or later installed:</p> <pre><code>pip install -U transformers[hf_xet] </tr></table> </code></pre> </blockquote> <p>...
